To all whom it may concern:

Be it known that I, MATHrAs M. APPLE- MAN, citizen of the United States, residing at Rohrsburg, in the county of Columbia and State of Pennsylvania, have invented certain new and useful Improvements in Churns, of which the following is a specification.

This invention contemplates certain new and useful improvements in churns of that type which are arranged for manual opera tion, and the object of the invention is an improved device of this character which is susceptible of being manipulated by a child or other inexperienced operator, and requires only intermittent impulses or exertions of power on the part of the operator, thus affording the latter short rests between times, and preventing the churning from becoming tedious and exhausting, and which embodies improved means for causing an oscillatory movement of the churn body after each impulse, so as to thoroughly agitate the cream and effect the formation of the butter with unusual facility.

With this and other objects in view that will more fully appear as the description proceeds, the invention consists in certain constructions and arrangements of the parts that I shall hereinafter fully describe, and then point out the novel features thereof in the appended claims.

For a full understanding of the invention and the merits thereof, and to acquire a knowledge of the details of construction, reference is to be had to the following descrip tion and accompanying drawings, in which:

Figure 1 is a perspective view of a churn constructed in accordance with my invention; Fig. 2 is a vertical section thereof; Fig. 3 is a perspective view with the churn body removed; Fig. 4 is top plan view of. the churn body with the top removed; Fig. 5 is a view in elevation of the stand; and, Fig. 6 is a top plan view thereof.

Corresponding and like parts are referred to in the following description and indicated in all the views of the drawings, by the same reference characters.

Referring to the drawings, the numeral 1 designates a preferably square churn body which is open at its upper end and is provided in its interior at opposite corners with diagonally extending perforated dasher plates 2-, the latter being designed to be rigidly mounted within the churn body, and in the present instance, being detachably secured therein by hooks 3.

4 designates a top or cover which is ar ranged to be supported in the open upper end of the churn body by means of cleats 5, so as to prevent the spilling of the cream during agitation, while at the same time being susceptible of being readily removed to permit the inspection of the contents at any time during the churning operation. The bottom of this churn body is secured between the sides thereof above the lower edges of said sides, so as to form a square recess 7 which is adapted to receive a substantially square platform or table 8 to detachably support the churn body upon the same and prevent any rotation of one of such parts relative to the other. The table 8 is secured to a cross bar 9 that carries a downwardly disposed vertical spindle 10 arranged to be journaled in a suitable support to rotatably support the churn body upon the same, said cross bar being also formed with depending stops 11 disposed on opposite sides of the spindle 10 for a purpose to be hereinafter set forth. In the present instance, the support for the churn body comprises a substantially stool-like stand 12 that isformed in its top with a centrally located opening 13 extending therethrough, the spindle 10 extending downwardly through said opening and being journaled in a bracket secured below the same, so as to support the churn body in superposed relation to the stand with the stops interposed between the same and the cross bar, as shown.

15 designates an actuating bar that is mounted upon the stand and extends across the same and is arranged in the path of rotation of the stops, tension springs 16 being secured at one end to the respective ends of such actuating bar and having their other ends secured to blocks 17 that are arranged to be adjustably secured to the top of the stand, and for this purpose are formed with longitudinally disposed slots 18 in which are mounted bolts 19 carried by the stand and susceptible of clamping the blocks securely in the desired positlon.

In the practical use of my improved churn, the operator grasps a handle 20 provided upon the churn body and turns the latter in one direction, say toward the right, to effect the partial rotation of such churn body about the spindle 10 and move the adjacent stop 11 against the actuating bar 15 and sub.- sequently carry the bar outwardly from the spindle 10 against the tension of the springs 16. The rotary impulse imparted to the churn body is terminated before the said stop has been swung past a center, and upon the releasing of the churn body by the operator, the actuating bar 15 is moved inwardly to assume its normal position, by the tension springs 16, whereby to carry inwardly the said stop against which it abuts, to effect the partial rotation of the churn body in the opposite direction. However, the rotary movement in this latter direction, is limited by the stop disposed upon the opposite side of the spindle, so that a number of partial rotations in opposite directions are attained in quick succession to oscillate the churn body and cause the cream in the same to pass back and forth through the dashers 2 and to become thoroughly agitated to separate the oily globules from the liquid. The above operation is repeated as often as is necessary to effeet the complete formation of the butter, and it will be seen that as it is only necessary for the operator to intermittently cause the partial rotation of the churn. body aganist the tension of the springs 16, the churning may be conveniently accomplished without the liability of the operator becoming fatigued, or without the necessity of a skilled attendant. By adjusting the blocks 17 upon the top of the stand, it will be obvious that long or short oscillatory strokes may be obtained, according as desired.

In the preferred construction of the stand, I secure strips 21 to the corresponding pairs of legs 22 thereof, and provide said strips with pads 23 of rubber or the like that are arranged for an adhesive contact or engage-. ment with the supporting surface, to prevent the stand from slipping thereupon during the churning operation.

Having thus described the invention, what I claim is:

1. In a churn, the combination of a rotary churn body, means for limiting the rotation thereof, and a yielding actuating bar cooperating with the limiting means to im art a rebounding rotary movement to t e churn body upon the turning thereof in one direc tion.

2. In a churn, the combination of a churn body having a dasher secured therein, a support upon which the body is rotatably mounted, means for limiting the rotation of the churn in each direction, and a spring actuating bar carried by the sup ort and arranged in the path of rotation of the limiting means and operating therewith to cause the churn body to rebound with an op osite rotary movement upon the turning t iereof in one direction.

3. In a churn, the combination of a churn body having a dasher secured therein, a su port upon which the body is rotatabl vmounted, the churn body being provided with stops disposed on opposite sides of the pivot, an actuating bar interposed between the churn body and the support and normally held in the path of rotation of the stops, and tension springs secured at one end to the support and at their other ends to the actuating bar and yieldingly sustaining the latter in its normal position, as and for the purpose specified.

4. In a churn, the combination of a churn body having a dasher secured therein, a support upon which the body is rotatably mounted, the churn body being provided with stops disposed on opposite sides of the pivot, an actuating bar interposed between the churn body and the support and normally held in the path of rotatlon of the stops, tension springs secured at one end to the actuating bar and arranged to yieldingly sustain the latter in its normal position, and blocks adjustably secured to the support and to which the tension springs are secured at their other ends.

5. In a churn, the combination with a churn body having a dasher secured therein and formed at its lower end with a recess, of a platform or table arranged to be received in the recess to detachably support the churn body, a vertical spindle secured to the platform, the latter being provided on opposite sides of the spindle with stops, a stand in which the spindle is journaled to rotatably support the churn body and the platform thereupon with the stops interposed between
